Tatuus - Korus Group

From 2026, the FIA Formula Regional European Championship will adopt the new Tatuus T-326, marking the introduction of the second generation of Formula Regional cars.


Monza, 24 October 2025

At the Temple of Speed in Monza, the brand-new Tatuus T-326 was unveiled. The single-seater that will take centre stage in the FIA Formula Regional European Championship, organized and promoted by ACI, starting from 2026.

The result of an intense development effort by Tatuus Racing, the T-326 (subject to FIA homologation) represents the second generation of Formula Regional cars, marking the evolution of the previous T-318, which since 2019 has accompanied the rise of many talented drivers such as Andrea Kimi Antonelli, Gabriel Bortoleto, Isack Hadjar and Franco Colapinto on their path towards the higher echelons of motorsport.

Aerodynamics and Performance

Developed in full compliance with the latest FIA regulations, the T-326 brings a major step forward in terms of performance, aerodynamics, and safety. The new car has been designed to be lighter, more stable, and more responsive, featuring an improved chassis architecture and a revised suspension system that enhances steering precision and overall balance through corners. Aerodynamic efficiency, inspired by the latest trends from top-level single-seater series, ensures increased overall downforce and reduced wake effect, improving overtaking opportunities and on-track racing quality. From 2026, the Championship will adopt Pirelli tyres as single supplier, fitted on new 15-inch OZ wheels, ensuring technical continuity and uniform performance across the grid.

ATM163T Engine: Power, Efficiency and Innovation

The T-326 will be powered by the brand-new ATM163T engine, developed by Autotecnica Motori and derived from the Toyota G16E unit. This represents the first three-cylinder engine ever introduced in Formula Regional history, developed in collaboration with TOM’S to deliver high performance combined with improved energy efficiency and reliability. The project fully aligns with the new FIA standards for sustainability and technological innovation.


Safety and Ergonomics at the Core

The next-generation chassis complies with the highest FIA safety standards, featuring reinforced structures and updated components such as new-design front and rear crash boxes, anti-intrusion panels, and a revised roll-over protection system. Inside the cockpit, the ergonomic configuration has been optimised to ensure a comfortable driving position suitable for a wide range of drivers, improving visibility, comfort, and overall driving experience.

Technical Partnerships

The T-326 has been developed in collaboration with a strong network of top-tier motorsport partners: ARS Tech, Giga Composite, Carbonmade and La Compositi for carbon fibre components; Breda Racing, Eibach and Andreani for the suspension system; PFC Brakes and Tilton for the braking system. On-board electronics have been developed in partnership with Marelli, Next Solution and Nope Engineering, while the package is completed by the Sadev SLR-82 gearbox, Sabelt harnesses, OMP safety systems, and components from Galletto and Gieffe, forming a technical platform of absolute excellence.

Following an initial testing phase between August and October involving several professional drivers and test specialists, the new Tatuus T-326 is now ready to take to the track. Its official debut in 2026 will mark the beginning of a new chapter in the history of the category, reaffirming its mission to nurture the next generation of international motorsport talents.

Weekend Preview: Tatuus takes on new challenges across four fronts
Weekend Preview: Tatuus takes on new challenges across four fronts
With titles still to be decided, close gaps in the standings and championships entering key stages of the season, Tatuus faces another weekend with plenty of different stories to follow.


Brands Hatch, Monza, Navarra and Jeddah will be the four focal points of the upcoming Tatuus weekend. British F4 and E4 reach their final rounds, Spanish F4 heads into its penultimate event, while F4 Saudi Arabia takes on the second round of its season. Four circuits and four different points in the year, with standings to watch, new names to keep an eye on and recent results set to shape the races ahead.


BRITISH F4

The 2026 British F4 season reaches its final round at Brands Hatch with the title still to be decided. Dries Van Langendonck arrives in a strong position, holding a 72-point advantage over Lewis Wherrell , but with 75 points still available across the three races, the championship remains mathematically undecided.

Van Langendonck has built his advantage with eight wins, three further podiums and four pole positions, while Wherrell heads into the final round with three victories this season and a chance to turn the standings around. The two drivers are also fighting for the Rookie Cup , where the Belgian holds a 23.5-point advantage over his rival.

These will not be the only battles to watch at Brands Hatch. Hitech leads the Teams' Cup by 83.5 points over Rodin Motorsport , while Theo Palmer , currently third in the drivers' standings, can still challenge for second place.

The final round comes at the end of a season that has produced 13 different race winners and 19 different podium finishers, with 42 drivers representing 21 nationalities.

Weekend schedule:
Saturday • 11:15 – Qualifying • 16:00 – Race 1
Sunday • 10:00 – Race 2 • 15:15 – Race 3
The races will be streamed live on the championship's official YouTube channel.


E4

Nine races, three events and a standings battle that will be settled over three final races at Monza. The E4 Championship heads into its final round with Kenzo Craigie leading on 138 points, while Luka Sammalisto is just 14 points behind. Alp Aksoy completes the top three on 112 points.

Craigie has been one of the standout surprises of the season. The Mercedes Junior driver with R-ace GP has claimed three wins and built his advantage race by race, but at Monza he will face an opponent arriving at the final round with a title already secured. Sammalisto wrapped up the Italian F4 championship with a round to spare and can now target a second title, matching the feat achieved by Kean Nakamura-Berta in 2025.

Aksoy, meanwhile, arrives at Monza with one win and third place in the standings to defend. The Turkish Prema driver will be one of the names to watch in a field that will reach 37 drivers for the final round, representing more than 20 nationalities and including several new faces.

Among them will be two young Prema drivers: 15-year-old Brazilian Victoria Farfus , who has experience in karting and Ginetta competition and has also taken part in the F1 Academy testing programme this year, and fellow 15-year-old Italian Filippo Sala , who comes from a strong karting background with BirelART and is a member of the Ferrari Driver Academy.

Monza will therefore bring together a highly international field for the final three races of the season. Craigie, Sammalisto and Aksoy will arrive with different objectives, while the newcomers will have their first opportunity to measure themselves against the E4 field.

Weekend schedule:
Friday • 17:20 – Qualifying
Saturday • 13:45 – Race 1
Sunday • 08:30 – Race 2 • 13:40 – Race 3
All sessions will be streamed live on the championship's YouTube channel


SPANISH F4

Spanish F4 heads to Navarra for the penultimate round of the season, with just 20 points separating the top three in the standings. Kasper Schormans leads the way on 182 points, but Noah Monteiro is only seven points behind, with Borys Lyzen a further 13 points back. With three races on the schedule, Navarra could significantly reshape the top of the standings ahead of the final round in Barcelona.

Monteiro will be one of the drivers to watch closely. After scoring podium finishes in all three races at Jerez, the Campos Racing driver has shown the consistency needed to close the gap at the top and will arrive in Navarra with a real opportunity to take the lead. Schormans, meanwhile, will be looking to protect his advantage, while Lyzen remains close enough to take advantage of any opportunity to move further into the fight.

Rocco Coronel also arrives in Navarra with momentum after winning the final race at Jerez, ending a long wait for another victory following his double win at the opening round in Valencia. It will be interesting to see whether he can maintain that return to the front at Navarra, with the Barcelona season finale only a few weeks away.

Weekend schedule:
Saturday • 09:00 – Qualifying 1 • 11:15 – Race 1 • 14:30 – Race 2
Sunday • 09:00 – Qualifying 2 • 13:00 – Race 3
The races will be streamed live on the championship's official YouTube channel:


F4 SAUDI ARABIA

F4 Saudi Arabia heads into its second round of the season in Jeddah, with the event taking place across Wednesday 7 and Thursday 8 of October. The opening race saw Marlon Bayer take victory ahead of Abdullah Kamel and Archie Owen , while F1 Academy driver Rachel Robertson finished tenth.

The second round is already underway: following the opening race in Jeddah, Thursday's programme features a second qualifying session and Race 2, providing another opportunity to follow the battle among the championship contenders.

Schedule:
Thursday • 16:50 – Qualifying 2 • 20:45 – Race 2

“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
The words of CEO Giovanni Delfino in an interview with la Repubblica.

The CEO of Tatuus, ATM – Autotecnica Motori, and the Korus Group was featured in an interview published today in la Repubblica and written by Irene Saderini. During the conversation, he reflected on some of the most important and defining moments of his career, while also sharing his views on several aspects of the global motorsport industry.
The full interview is available on repubblica.it .

A Personal Journey A central theme of the interview is the CEO’s personal story, which began with his decision to pursue engineering studies and continued through a career marked by bold choices and decisive moments: “I don’t believe in luck; I believe in being able to seize it. When an opportunity comes your way, you have to recognize it. That said, it would be unfair to claim I wasn’t fortunate. I joined the company when I had virtually nothing. The founder allowed me to repay my debt over time, and I only finished paying the last installments two or three years ago.”
Delfino also spoke about his early years at Alfa Corse, where he developed his passion for experimentation and performance engineering: “At heart, I am a track engineer. I worked in the testing departments, where our job was to find that extra half horsepower from a finished product. My first experiences came in Alfa Romeo Touring Cars, with drivers such as Giovanardi, Tarquini and Larini competing against BMW and Mercedes. Sometimes those extra two horsepower were what won you the race.”

Formula 4 and Driver Development Among the key topics discussed was the production of Formula racing cars and engines, today one of the cornerstones of the Korus Group: “Everything starts with studying the regulations, which always leave room for interpretation—and success comes from finding the right one.” Speaking about Formula 4 engines, Delfino explained: “It all starts with a four-cylinder Fiat 500 Abarth unit. It must cost less than €16,500 due to the price cap and last 10,000 kilometres. My objective is to ensure that every engine performs the same.” The reward is seeing young talents progress step by step through the motorsport ladder and ultimately reach the highest levels of the sport: “It was particularly rewarding to see Andrea Kimi Antonelli begin his career in one of our cars.”

The Motorsport Industry The interview also included a broader reflection on the remarkable momentum motorsport is experiencing worldwide: “Motorsport sometimes works like a kind of magic, capable of overcoming marketing logic and keeping alive that uniquely Italian determination to believe in something even when the numbers don’t add up.”
Particularly representative of the Korus Group’s vision was Delfino’s perspective on internal combustion and electric powertrains: “For me, the smell of a winning engine is the smell of gasoline, hard work and sacrifice. A twelve-cylinder engine on track is like a violin—actually, an entire orchestra of violins. Racing is my world, and I find it difficult to see any of that emotion in batteries alone. Hybrid technology, however, is a different story. We are part of the FIA working group on the new regulations, and I find the hybrid approach very compelling.”

Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
The Lainate-based manufacturer has celebrated the production and delivery of the 500th chassis of the single-seater on which Kimi Antonelli and Arvid Lindblad developed their careers.

Born in 2021, the Tatuus T-421 reached its 500th unit produced and delivered in May 2026, once again confirming its status as one of the most manufactured and successful racing single-seaters worldwide. The milestone was celebrated by the Lainate-based brand together with all its employees and the sister companies of the Korus group, which contribute daily to the T-421 project: ATM–Autotecnica Motori, Breda Racing, and Next Solution Technologies.
Today, the T-421 is the most widely used Formula 4 car in the world, competing across 16 championships spanning Europe, the Americas, Asia, and Oceania. Behind its wheel, some of the most exciting talents in contemporary motorsport have developed, including Kimi Antonelli and Arvid Lindblad , who built the first steps of their single-seater careers in the second-generation Tatuus F4 before progressing all the way to the pinnacle of Formula 1.
“The 500th T-421 is not only a major milestone for Tatuus, but also an important achievement for the entire international motorsport ecosystem,” said Giovanni Delfino, CEO of Tatuus and the Korus Group. “With the introduction of Formula 4 in 2014, the FIA created a new pathway between karting and single-seaters, enabling drivers to arrive better prepared for higher categories. This model has established itself through years of significant growth in motorsport, during which many championships were launched and expanded, now reaching grids of nearly 50 cars per round with the second generation we celebrate today. These are figures that were difficult to imagine at the beginning of this journey, but which now define the everyday reality of many of the companies within the Korus Group.”
“Throughout Tatuus’ history, many of our models have achieved widespread adoption across global championships and have demonstrated unparalleled driver development capabilities,” added Gianfranco De Bellis, President of Tatuus and the Korus group. “The T-421 is writing an important chapter in the history of our brand and, together with the first-generation car, is now approaching 800 units produced. These volumes allow us to aim toward the milestone of 1,000 F4 single-seaters, a figure previously approached by the various Formula Renault models that marked a turning point in our history and in the development path of many drivers.”
As the second generation of Formula 4 single-seaters, the T-421 succeeded the T-014, which from 2014—the year Formula 4 was introduced—through 2021 was produced in just under 300 units. It represented the ideal platform for drivers transitioning from karting to single-seaters, and helped develop talents such as Lando Norris, Oscar Piastri, Max Verstappen, Isack Hadjar, Liam Lawson, Lance Stroll, Oliver Bearman, Gabriel Bortoleto, and Franco Colapinto.
The T-421 is just one of many examples of the cooperation that makes the Korus group one of the leading global ecosystems in motorsport engineering. The companies within the Group involved in the celebration have contributed to the project from day one, within a consolidated model of synergies that each year gives rise to new cars, powertrains, and solutions for motorsport.
Specifically, ATM–Autotecnica Motori developed and supplies the Abarth-derived inline four-cylinder engine that powers the car, while Breda Racing is responsible for a large portion of the components—such as the halo and suspension arms—as well as instrumentation required for managing the cars both on track and at HQ. Next Solution Technologies provides a significant part of the car’s electronic and electromechanical systems, in addition to supplying steering wheels and rain lights.
However, the milestone of 500 cars does not represent a finishing point for Tatuus. Production of the current model will continue through 2028 , when FIA regulations foresee the introduction of the third-generation car , on which the brands of the Korus Group are already actively working.
